Description

[Detailed description of the invention] This invention is based on the idea that concrete plates such as precast concrete plates (hereinafter referred to as 20 plates) or metal This relates to a curtain wall made up of panels such as plates, and is intended to improve ease of installation and accuracy of positioning.

Conventionally, in this type of curtain wall, the plates were attached directly to the frame, making positioning difficult.Moreover, the plates were individually identified by bolts or welding, making installation cumbersome.

In addition, with conventional construction methods, it is difficult to divide the slabs of this type of curtain wall in the height direction of the building, and it is difficult to divide the plates of this type of curtain wall in the building height direction.
unit or at most 2 units,
The size of the plate was large, and due to the weight of the plate, it was not possible to improve work efficiency.

This invention was made with the intention of solving the above-mentioned problem, and its gist is that the mullions installed vertically at appropriate intervals are used to position the level and surface for holding the plate. An external positioning bracket is attached, and an upper fixing bracket is inserted between the plate to be engaged with the bracket and the mullion to fix the plate to the mullion. Since the plate is attached via a mullion that is attached to the exposed slab, positioning is easy.Moreover, it is easy to install because no fixing means such as bolts or welding is used. Since the plate can be divided freely, the plate can be made into a small unit and lightweight, improving work efficiency.

Examples of this invention will be described below with reference to the drawings.

In the figure, 1 is a slab, 2 is a mullion that is vertically attached to the slab 1 at appropriate intervals, and 3 is a PC plate as a plate that is attached via the mullion 2. The following describes the case where the version is a PC version.

A level positioning bracket 4 and an out-of-plane positioning bracket 5 are attached to the mullion 2, and are also used to maintain airtightness between the 20-plate 3 and the mullion 2, and to position the 20-plate 3 in the out-of-plane direction. A gasket 6 is attached to the brackets 4 and 5 and the gasket 6 for the
0 version 3 is maintained.

The 20th edition 3 has a rectangular shape as a whole, and the side surfaces are stepped so that the indoor side is narrower than the outdoor side, and grooves 3a and 3b are formed on both sides of the upper and lower ends of the stepped portion. has been done.

The level positioning bracket 4 is attached to the fixing piece 4a to the mullion 2 and the 40 plate 3 so as to receive the weight of the 40 plate 3 and at the same time level the 40 plate 3 when the 20 plate is installed.
The receiving piece 4b that supports the lower surface of the receiver is configured in an L-shape (
2 and 5), the fixing piece 5a of the out-of-plane positioning bracket 5, which is also configured in an L-shape, is fixed to the mullion 2 by overlapping the fixing piece 4a, and the retaining piece 5b is fixed to the mullion 2. The 40 plate 3 is inserted into the groove 3b provided at the lower end of the frame, is bent into an arc shape to draw the 40 plate 3 toward the indoor side, and prevents it from falling out of the plane, and is attached to the mullion 2. It is formed to perform positioning in the out-of-plane direction with a gasket 6 (FIGS. 2 and 6).

In this case, the level positioning bracket 4 and the out-of-plane positioning bracket 5 are formed separately, but they can also be formed integrally.

Reference numeral 7 denotes an upper fixing bracket, which is generally L-shaped as a whole as shown in FIG. 7, and has both pieces 7a.

Both pieces 7b are curved into an arc shape, and one piece 7a is the fourth piece.
As shown in the figure, the 40 plate 3 is inserted into the groove 3a provided at the upper end of the 40 plate 3, and the other piece 7b is inserted into the groove 2a of the mullion 2 to draw the 40 plate 3 toward the indoor side. At the same time as preventing the 40 plate 3 from falling out of the plane, the gasket 6
It is also formed to perform positioning in the out-of-plane direction.

(Figure 4). The gasket 6 is attached to surround the outdoor side flange of the mullion 2, and serves as a watertight material between the 40 plate 3 and the mullion 2, and at the same time works together with the out-of-plane positioning bracket 5 and the upper fixing bracket 7. , 40 plate 3, and its cross-sectional shape is shown in FIG. 8.

As shown in FIG. 9, the 40 plate 3 has grooves 3a and 3b on both sides of its upper and lower ends, into which the upper fixing bracket 7 and out-of-plane positioning bracket 5 are inserted, respectively.

Note that a backing 8 is interposed between the upper and lower joints of the 40 plate 3 (Fig. 10), and this backing 8 allows the P.
This prevents rainwater etc. from entering between the C plates.

Next, the curtain wall of this invention formed by the above-mentioned members will be explained according to the construction outline. First, the mullion 2 to which the level positioning brackets I/4 and the out-of-plane positioning brackets 5 have been attached in advance is 1, and the 40 plate 3 is placed on the level positioning bracket 4 while being aligned with the out-of-plane positioning bracket 5.

Next, 3a provided at the upper end of 40 plate 3 and mullion 2
Insert the PC plate upper fixing bracket 7 into the groove 2a (Fig. 4), press the 40 plate 3 toward the room against the gasket 6 attached to the mullion 2, and fix it to the mullion 2. .

Thereafter, similarly, 40 plates 3 are sequentially attached to form a wall surface.

In this case, the manner in which the 40 plate 3 is installed may be one unit between the slabs 1, as shown in FIG.
As shown in Figures 1 to 1d, it is also possible to divide and install 2 to n units between slabs.

In the curtain wall of this invention constructed as described above, the plate is attached through the mullion 2 that is attached perpendicularly to the slab 1, so positioning is easy, and there is no need to use bolts or welds. It is easy to install because it does not require fixing means such as By making the unit lighter, work efficiency can be further improved.
